Abstract
New zero correlation window (ZCW) LS (loosely synchronous) codes derived from basic LS codes are constructed. A general scheme for generating these codes is also discussed. It is showed mathematically that these new codes have a uniform ZCW for both aperiodic auto-correlation function (ACF) and cross-correlation function (CCF) within one group. Moreover, the minimum ZCW among different groups is the same as that of basic LS codes. The number of these new codes is more than the basic LS codes, and code efficiency can be greatly enhanced. Finally, the computer simulations verify the validity of new LS codes.
